You can make high quality quality digital prints from negatives and slides. I knew a retired Vogue photographer who made gallery quality large prints from his old old Vogue slides. He had a special scanner and printer. There will be many places than can do this type of work for you. You can even try and scan it yourself if you have a home scanner-- see how that comes out.

I don't know if it's proper conservation technique or not, but I met another pretty famous Vogue photographer who kept his old film negatives in normal little manilla paper envelopes. I assume he knew what he was doing.
